How to get bitcoind to auto-download?

I am trying to run the BitcoinCoreClientSpec tests and I get the following error:

An exception or error caused a run to abort: Cannot run program "/home/ben/projects/eclair/target/bitcoin-0.21.1/bin/bitcoind": error=2, No such file or directory

nevermind was able to get it with mvn verify, intellij just wasn't downloading it for me

Yes, maven test would work too. You will have to run this every time you clean the target directory (manually or with mvn clean).
